Focusing purely on the numbers.Opportunity Cost of Renting: No AppreciationLet’s start by understanding the concept of appreciation in the context of real estate.

One says we need to "perform a 1031" the other said that it is essentially a pure exchange and no action is needed for my dad since it is an exchange and no money is changing hands.  

Pure laziness I guess.

Very sound words from a pure business economics standpoint. 

That flips as you add units, anything 5+ for example the market for buyers is near 100% pure investor - so value will be mostly determined by rental potential (cap rate)

LLC creation for rental properties is purely a liability protection strategy. 

If you're looking at just a pure financial perspective with little/no room for personal comforts, the absolute best thing you can do is live in one of those tiny homes or something like that.

Echoing what most said here but I purely would analyze the numbers. 

This way buyers can then shop buyer agents and the commission should be negotiated purely between buyers and buyer's agents which would result in zero possible collusion. 

The fact that Denver makes it vague and unclear so they can use it against us, is absolutely pure BS.
